Patent number: 9048573Abstract: An interconnect system (30, 100) includes a transceiver module assembly (105) that is mountable in an industrial receptacle (28, 103). The receptacle mates to an industrial optical connector (34) to form an environmentally sealed connection. The receptacle has an interior passageway (143, 162) and mating means (124) for attaching the module assembly. The module assembly includes a spring-loaded module cage (50) for receiving active devices (48), such as SFP transceivers. The spring-loaded module cage can adjust its position within the receptacle to accommodate different type of modules from various vendors. When attached to the platform, the module assembly is positioned so that the cage's open end is accessible through the receptacle's passageway. Users have the option of plugging/unplugging the transceiver module either through the passageway or by removing the module assembly from the receptacle.Type: GrantFiled: August 15, 2006Date of Patent: June 2, 2015Assignee: Molex IncorporatedInventors: Barbara Grzegorzewska, Thomas R. Marrapode, Bogdan Andrei, David S. Rifkin

Patent number: 8678671Abstract: A tool for cleaving a plastic optical fiber has a body with a cleaving aperture at the insertion face of the body and through which the termination end section of the plastic optical fiber is inserted and in which an operative section is positioned upon inserting the plastic optical fiber into the tool. A cutting blade has a cutting edge and is moveable along a cutting path between a first operative position at which the cutting edge is spaced from the cleaving axis and a second operative position at which the cutting edge intersects the cleaving axis to cleave the plastic optical fiber to create an optical finish on an end surface of the operative section of the plastic optical fiber. A clearance region is located at the termination face of the body and generally aligned with the cleaving aperture and in which the termination end section may deflect upon engagement of the cutting blade with the plastic optical fiber.Type: GrantFiled: February 23, 2009Date of Patent: March 25, 2014Assignee: Molex IncorporatedInventors: Paul M.
